Attribute substitution not working in templates for dynamic lists

Question

Hi all,
dynamic lists were introduced in APEX 4.1 and they can be used for drop-down menus. I am trying to use attribute substitution #A01#...#A10# in the templates without success.
Here is a sample select statement
<pre>
SELECT level,
short_title label,
'f?p=myapp:1:0::::MYAPP_ID:'||id target,
'NO' is_current,
NULL image,
'm'||TO_CHAR(id) attribute1
FROM mytable
START WITH parent_id = :MYAPP_ROOT_ID
CONNECT BY PRIOR id = parent_id
ORDER SIBLINGS BY seq_in_parent
</pre>
and here a snippet from the template
List Template Noncurrent
&lt;li class=&quot;dhtmlMenuItem&quot;&gt;&lt;a id=&quot;#A01#&quot; href=&quot;#LINK#&quot;&gt;#TEXT#&lt;/a&gt;&lt;/li&gt;
The substitution is not being made. It looks like a bug but maybe I'm missing something.
Any help would be greatly appreciated.
Regards Garry

Hi Garry,
When the list query is parsed, it's not the column alias that deciphers which parameters you're trying to set, it's the positioning of the parameter in the query itself. So, for example, if a user wishes to set the #A01# attribute, like in your case, then the value returned by the 8th parameter in the query will be used. In your original query, you only supplied 6 parameters i.e. up to the image attribute setting. If you're not setting anything for the image attributes, then you simply set those values to null. The syntax for the query should be similar to the following:
select level,
       labelValue               label,
       [targetValue]            target,
       [is_current]             is_current_list_entry,
       [imageValue]             image,
       [imageAttributeValue]    image_attribute,
       [imageAltValue]          image_alt_attribute,
       [attribute1]             attribute1,
       [attribute2]             attribute2,
       [attribute3]             attribute3,
       [attribute4]             attribute4,
       [attribute5]             attribute5,
       [attribute6]             attribute6,
       [attribute7]             attribute7,
       [attribute8]             attribute8,
       [attribute9]             attribute9,
       [attribute10]            attribute10
